Description
Technical field
The present invention relates to a kind of reciprocating saw, particularly relate to a kind of reciprocating lever parts of reciprocating saw.
Background technology
Reciprocating saw generally includes motor, gear transmission part, reciprocating lever parts, is arranged on the fork parts between gear transmission part and reciprocating lever parts and is driven the saw blade moved back and forth by reciprocating lever parts.Wherein, reciprocating lever only needs the free degree along its axis, and in order to limit its radial and axial rotary freedom, reciprocating saw also arranges positioner usually on reciprocating lever.The end that a kind of positioner of the prior art is included in reciprocating lever welds a stopper, a pair locating part of the one-body molded both sides at stopper and the sleeve pipe that is arranged on reciprocating saw.This sleeve pipe is provided with chute, and above-mentioned locating part can be slidably matched in sleeve pipe along this chute.
But stopper in above-mentioned positioner adopts steel-casting, its profile difficulty processing and need to be welded on reciprocating lever, thus manufacturing process's more complicated and cost is higher; In addition, the mating surface between this locating part and sleeve pipe is less, is easily worn, so shorten the service life of reciprocating lever parts.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of cheap for manufacturing cost and reciprocating lever parts of the reciprocating saw that service life is longer.
In order to solve the problems of the technologies described above, the present invention is obtained by following technical proposals and solves: a kind of reciprocating lever parts of reciprocating saw, comprise reciprocating lever, the positioner of the knife-clamping device being arranged on one end of reciprocating lever and the other end being arranged on reciprocating lever, it is characterized in that: described positioner comprises the alignment pin be fixedly mounted on described reciprocating lever, be removably mounted on a pair slide block at the two ends of described alignment pin, and the sleeve pipe be fixedly mounted on the housing of described reciprocating saw, when described reciprocating lever is reciprocating, described slide block slides along the inwall of described sleeve pipe.
In addition, the present invention also proposes following attached technical scheme:
Described reciprocating lever arranges through hole, described alignment pin and described through hole phase interference fit.
Described alignment pin is mutually vertical with described reciprocating lever.
Described slide block is dismountable to be set on described alignment pin.
Described slide block can rotate relative to described alignment pin.
The inwall of described sleeve pipe is provided with chute, and described slide block can slide in described chute.
The shape of described slide block is roughly rectangle, and is made up of powder metallurgy.
Compared with prior art, the invention has the advantages that: reciprocating lever parts provided by the present invention, positioner is wherein by being fixedly mounted on the alignment pin on described reciprocating lever, a pair slide block being removably mounted on the two ends of described alignment pin and the sleeve pipe be fixedly mounted on the housing of described reciprocating saw, described slide block slides along the inwall of described sleeve pipe, contact area between such slide block and sleeve pipe is larger, more wear-resisting, therefore long service life, those parts machining manufactures are simple, cost compare is cheap.

Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
With reference to Fig. 1, corresponding to the reciprocating saw of present pre-ferred embodiments, it is mainly used in cutting timber, and comprises motor 20, gear transmission part 31, reciprocating lever parts 34, be arranged on the fork parts 38 between gear transmission part 31 and reciprocating lever parts 34 and driven the saw blade 14 moved back and forth by reciprocating lever parts 34.
With further reference to Fig. 2 to Fig. 4, above-mentioned reciprocating lever parts 34, comprise reciprocating lever 13, be arranged on the knife-clamping device 9 of one end of reciprocating lever and be arranged on the positioner 11 of the other end of reciprocating lever, wherein knife-clamping device 9 is matched with above-mentioned saw blade 14.These reciprocating lever parts 34 are supported on the enclosure interior of machine by bearing block 17.Reciprocating lever 13 is one-body molded reciprocating lever plug 18, and one end of above-mentioned fork parts 38 is inserted in this reciprocating lever plug 18, for reciprocating lever 13 provides reciprocating force.
The sleeve pipe 10 that above-mentioned positioner 11 comprises the alignment pin 7 be fixedly mounted on reciprocating lever, is removably mounted on a pair slide block 8 at the two ends of alignment pin 7 and is fixedly mounted on the housing of described reciprocating saw, when described reciprocating lever 13 is reciprocating, described slide block 8 slides along the inwall of described sleeve pipe 10.Particularly, reciprocating lever 13 arranges through hole 15 on the direction perpendicular to its axial B, described alignment pin 7 and described through hole 15 phase interference fit, and alignment pin 7 is mutually vertical with reciprocating lever 13.In addition, the two ends of alignment pin 7 are given prominence to respectively outside through hole 15, above-mentioned this to slide block 8 dismountable two ends being set in described alignment pin 7 respectively.The shape of described slide block 8 is roughly rectangle, and is made up of powder metallurgy.The inwall of described sleeve pipe 10 is provided with chute 12, and described slide block 8 can slide in described chute 12.Like this, by the setting of rectangular shaped slider 8 of being made up of powder metallurgy, slide block 8 is set on alignment pin 7, and can relatively rotate between slide block 8 and alignment pin 7, when making reciprocating saw have a longitudinal oscillation when cutting, slide block 8 can not be suppressed extremely in sleeve pipe 10, and the contact area between slide block 8 and sleeve pipe 10 is large, more wear-resisting, therefore service life is longer, and its processing and manufacturing cost compare is cheap.
It is pointed out that above-mentioned preferred embodiment is only and technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
